A grill roughly speaking raditation following operation?
I am having surgery this following week to remove part of my stomach tissue due to stomach sarcoma. After they operate, they will end beside radiation to be sure the ares is clear. How exactly does radiation work? I feel silly for asking this, but the doctor didn't full explain what it was, he just explained what it did.
Answers: ii work as a radiation psychoanalyst (the person who administers the radiation) so i can answer this but i would need to know what charitable of treatment you are getting. when you say they will end with radiation do you be set to you are getting intra-operative radiation? meaning radiation during the surgery? or will you be getting external beam or brachytherapy treatments after the surgery? if you let me know more i can tolerate you know exactly what will happen.
with brachytherapy the radiation will be administered from inside the body. this can be done 2 ways. the first is with LDR (low dose rate) radiation. a catheter(or more than one) will be placed inside the tumor bed nouns. then radioactive seeds will be inserted into the catheter and left inside the body for a predetermined amount of time. this amount of time will depend on the dose of radiation to be precise prescribed and will be calculated by the physicist/dosimetrist. this will probably be for a few days. during this time you will have a live radioactive source inside your body so certain precautions will have to be made. the radiation does not travel markedly far so you do not have to worry about people being exposed as long as they are at a safe distance from you. (ie. no sitting on your lap) the fact that the radiation does not travel far also technique that other organs of your body will not be effected by the treatment. surrounding tissues will get some radiation but these will be within tolerance. (meaning that they will not attain enough dose to do damage) when the treatment time is up then the catheters and seeds are removed.
the second means of access is similar but takes place entirely during surgery. HDR(high dose rate) radiaion is given directly to the tumor site right after the tumor is removed.
in this case "low dose rate" and "elevated dose rate" are referring to the amount of time it takes for the prescribed dose of radiation to be delivered-not to a low or high prescribed dose. it just depends on the type of radioactive source used.
n a minute how does radiation work: the radiation works on a cellular level. both healthy and cancerous cells will be effect. cancer cells are basically mutated cells and do not hold the ability to repair or replicate themselves effectively after being damaged by radiation. the fighting fit cells, on the other hand, can repair and reproduce. so the cancer cells die bad and are replaced by the healthy cells. there is a great deal of work going on inside the body and that is why one of the common side effects from radiation is fatigue. raditation is often used within addition to surgery to make sure that any microscopic disease is treated. the tumor margins may be clear (meaning they got adjectives the cancer out) but that is referring to cancer that can be seen at this time. there may be cancer cell that cannot be seen yet and that is why the radiation is given.
i hope this answers your examine. good luck to you.
